Modern smartphone users are increasingly paying attention to the quality of wireless sound, trying to get maximum performance from their devices. The standard SBC codec, which is used by default in the Bluetooth protocol, is often insufficient to transmit detailed high-definition audio. This is where the technology LDACdeveloped by Sony comes into the picture, which allows you to transmit an audio stream with a bitrate of up to 990 kbps.
Many owners of Android gadgets are wondering how to forcefully enable this mode if the system does not offer such an option in the standard menu. It is important to understand that codec support depends not only on the version of the operating system, but also on the hardware capabilities of your smartphone and headphones. In this article we will analyze all the nuances of activation, possible limitations and hidden configuration methods.
Before moving on to complex manipulations, you need to make sure the basic compatibility of your equipment. Without hardware support for the chipset, software methods may be useless or lead to unstable operation of the audio system. Let's take a closer look at what exactly is required for this standard to work.
Checking compatibility of hardware and Android version
High-resolution audio technology has become a native part of the Android ecosystem starting with version 8.0 Oreo. If your device has an older version of the system installed, native support LDAC will not be available, and its implementation will require third-party solutions or flashing. However, having a new OS version does not guarantee the codec will work, as manufacturers often disable this feature on budget models.
The key factor is the Bluetooth chip of your smartphone. It must support data transfer at high speeds without packet loss. Even if the specifications indicate the presence of Bluetooth 5.0 or higher, this does not always mean support for advanced codecs. You need to check the manufacturer's official documentation or technical reviews for your model.
It is also critical that the receiving device - your headphones or speaker - also supports this standard. The connection is always established according to the principle of the lowest common denominator: if one of the devices does not support Hi-Res Audio, the system will automatically switch to a simpler codec such as AAC or SBC.
☑️ Check before installation
It is worth noting that some manufacturers, such as Xiaomi or Realme, may hide this option in their shells MIUI or RealmeUI, even with hardware support. In such cases, activation is possible only through the engineering menu or third-party utilities.
Activation through the menu for developers
The safest and recommended way to enable advanced codecs is to use the built-in menu for developers. This method does not require Rooting and does not violate the device's warranty, however, the option may be hidden if the system does not see a compatible audio device.
First, you need to activate the hidden settings section. Go to the menu Settings → About phone and find the item Build number. Click on it quickly seven times in a row until a notification appears indicating that you have become a developer. After this, a new section will appear in the main settings menu.
Go to System → For developers and scroll down the list to the “Network” or “Media” section. Find item Bluetooth LDAC codec. If this item is active (not greyed out), you can select the desired data transfer mode. Typically, three options are available: audio quality priority, balanced mode and connection priority.
⚠️ Attention: If the codec selection item is grayed out or missing, this means that there is not currently a compatible device connected to your smartphone, or your phone's chipset does not physically support it technology.
Selecting a mode 990 kbps provides the best sound quality, but may lead to increased audio latency and increased battery consumption. In conditions of strong radio interference, for example in the subway or crowded places, the connection may become unstable, and the system will be forced to lower the bitrate automatically.
To check the current active codec, you can use the free Bluetooth Codec Changer application or similar utilities from Google Play, which display the actual bit rate in real time.
Using third-party applications to force inclusion
In situations where the standard menu does not provide the necessary options, specialized utilities from the Google Play store come to the rescue. Applications like Bluetooth Codec Changer or Lesser AudioSwitch allow you to interact with system audio drivers and force codec switching.
Most of these apps work without root access, using special ADB permissions or system APIs. After installing the application, you need to give it rights to change system settings. In the app interface you will see a list of available codecs, where you need to select LDAC and click the apply button.
However, the effectiveness of these methods directly depends on the security policy of your version of Android. On newer versions of the system, such as Android 13 or 14, access to low-level audio settings may be limited. In this case, the application may show the codec as available, but the actual switching will not occur.
Some applications require a connection to a computer to grant permissions via USB debugging. This may be inconvenient for the average user, but is often the only way to bypass the manufacturer's shell restrictions.
Configuration via ADB and system commands
For advanced users who are not afraid of working with the command line, there is a method of forcing activation through the Android Debug Bridge (ADB). This method allows you to make changes to global system settings that are not accessible through the GUI.
You will need to install ADB drivers on your computer and enable USB debugging on your smartphone. Once your device is connected, run the following command in a terminal to check your current Bluetooth settings:
adb shell settings get global bluetooth_codec_configYou can use global settings commands to force high bitrate to be enabled, although modern versions of Android often block direct writing to this setting. An alternative way is to use commands to change the priorities of codecs in the system:
adb shell cmd bluetooth_manager set_codec_config_preference ldacThis method gives the greatest control over the system, but carries risks. Entering commands incorrectly can cause the sound in the headphones to disappear completely, and you will have to reset the network settings or perform a complete reset of the device.
What to do if the command is not executed?
If the terminal displays the error 'Permission denied' or 'Security exception', then your firmware is blocking changes to these parameters without root access. In this case, try temporarily granting permissions through the Shizuku app.
Problems with connection stability and delays
Using a high bitrate codec places a serious load on the Bluetooth radio channel. Users often experience audio artifacts, crackling noises, or intermittent connection dropouts when in active mode. 990 kbps. This is especially true in areas with a large number of other wireless devices.
Audio latency (latency) when using LDAC is significantly higher than when using SBC or aptX Low Latency codecs. This makes the technology unsuitable for mobile gaming or watching videos without support for latency compensation functions on the player side. The sound may lag behind the picture by 100-200 milliseconds.
To minimize problems, it is recommended to use a balanced data transfer mode, which dynamically adapts the bitrate depending on the signal quality. This allows you to maintain high sound quality in static conditions and avoid interruptions in motion.
| Operating mode | Bitrate (kbit/s) | Sound quality | Stability |
|---|---|---|---|
| Priority quality | 990 | Maximum (Hi-Res) | Low |
| Balanced | 660 | High | Medium |
| Priority connections | 330 | Standard | High |
| SBC (basic) | 328 | Basic | Very high |
⚠️ Attention: Bluetooth settings interfaces and menu item names may differ depending on the Android version and smartphone model. Always check the latest documentation from your manufacturer, as settings may be renamed or moved in security updates.
Impact on device battery life
Transferring more data requires more intensive operation of the Bluetooth module, which inevitably affects power consumption. With active use of the maximum quality mode, the operating time of the smartphone on a single charge can be reduced by 10-15% compared to the standard codec.
It is also worth considering that headphones in high-flow reception mode also consume more energy. If your headphones have a small battery capacity, their battery life LDAC may be critically low. This is an important factor for those who use a headset on long trips.
Many modern players and smartphones automatically turn off high-bitrate codecs when the battery level is low to save energy. This behavior can be considered a protective mechanism that prevents the device from suddenly turning off at an important moment.
The use of LDAC is justified only when listening to lossless files on high-quality acoustics; for podcasts and streaming in low quality, the difference will be unnoticeable, and battery consumption will increase.
Frequently asked questions (FAQ)
Why doesn’t my phone see the LDAC codec, although my headphones support it?
Most likely, your smartphone does not support this standard in hardware, or the Android version is too old (below 8.0). Also check to see if Power Saving Mode is enabled, which often disables advanced Bluetooth features.
Can you install LDAC on an iPhone?
No, the Apple ecosystem uses its own AAC codec and does not support LDAC natively. To use LDAC on Apple devices, you will need special external DAC adapters that support this standard.
Does the Bluetooth version affect the operation of the codec?
Yes, for stable operation of LDAC, Bluetooth version 4.2 or higher is desirable. Older versions may not provide the necessary channel bandwidth to transmit a 990 kbps stream.
Are root access needed to enable LDAC?
In most cases, on modern smartphones with Android 8.0+, root access is not needed if the function is supported by the hardware. The developer menu is enough. Root may only be required for older devices or specific Chinese firmware.
Will the quality of calls deteriorate when LDAC is enabled?
No, codecs for transmitting music and voice calls work independently. During a telephone conversation, the system will automatically switch to the HFP voice profile, regardless of the media codec settings.
